With the promotion of energy conservation and emission reduction on the whole country, the cooler for brewing wine gradually develops towards energy conservation, advocates water conservation and reduces water resource pollution, and has practical significance. In order to achieve the purposes of saving water, reducing emission and accurately controlling the temperature of the discharged wine, the traditional water-cooled cooler is gradually replaced by various automatic air coolers, such as an air cooler with a horizontally-mounted condenser pipe (e.g. a variable-frequency constant-temperature cooler with a cooling device in patent number 201520453615) and a vertical air cooler with a vertically-mounted condenser pipe (e.g. a novel air-cooled condenser for brewing wine in patent number 201210393573.6). The condenser pipe of horizontal air cooler adopts the mounting means of horizontal slope, and the condensation pipeline often adopts the multiple pass to arrange, causes pocket wine (unable exhaust wine that remains) easily in condenser pipe connection chamber and condenser pipe, influences the quality of wine, makes its quality decline, has been replaced by vertical air cooler gradually.
